    1. Arguably what is in­ter­est­ing about Svelte’s approach to state man­age­ment is not the store itself but the auto-sub­scrip­tion that is possible because of the Svelte compiler. By simply appending a $ to a variable inside of a component, e.g. $myVariable, the compiler will know to expect an object with a subscribe method on it and generate the boil­er­plate of sub­scrib­ing and un­sub­scrib­ing for you.

    1. Links are just <a> elements, rather than framework-specific <Link> components. That means, for example, that this link right here, despite being inside a blob of markdown, works with the router as you'd expect

    1. But that's a lot of code to write, so Svelte gives us an equivalent shorthand — an on:message event directive without a value means 'forward all message events'.
    1. preventDefault — calls event.preventDefault() before running the handler. Useful for client-side form handling, for example. stopPropagation — calls event.stopPropagation(), preventing the event reaching the next element passive — improves scrolling performance on touch/wheel events (Svelte will add it automatically where it's safe to do so) capture — fires the handler during the capture phase instead of the bubbling phase (MDN docs) once — remove the handler after the first time it runs self — only trigger handler if event.target is the element itself
    1. Why don't you allow a range without end, like (1..)? There are two advantages. First, we can write ary[1..] instead of ary[1..-1]. The -1 is one of the most I dislike in Ruby. It is very magical, ugly, redundant, and disappointing. I envy Python's ary[1:]. I know that ary.drop(1) is slightly fast, but too long for such a common operation, IMO. Second, we can write (1..).each {|n| ... }.
    1. Shorthand attributes It's not uncommon to have an attribute where the name and value are the same, like src={src}. Svelte gives us a convenient shorthand for these cases: <img {src} alt="A man dances.">
